The grains are sent to the lower part of the grain lifting tower 40 of No. 4, fried by the packet conveyor 42 in the grain raising tower 40, and discharged into the discharge cylinder part 41,
When the shutter 5 is opened in advance to be guided from the opening 1150 to the take-out gutter 43 to take it out of the machine, when the work is finished, it is placed in the conveying gutter 3 of the upper conveyor a. A small amount of grain inevitably remains. Since leaving the remaining grains unattended may cause inconveniences such as being harmed by mice, a means is provided to remove the remaining grains from the machine.

This can be accomplished by providing an open opening at the bottom of the conveying gutter 3 exposed inside the grain tank 10 and providing there with a shutter that slides in the longitudinal direction of the conveying gutter 3, or by using a conveying gutter 3 that closes the open opening. The bottom plate of the bottom plate is made to rotate downward with one end of the bottom plate in the longitudinal direction as a rotation fulcrum, or the other side edge is rotated downward with one of the longitudinal edges as a fulcrum. For example,

Therefore, the upper conveyor a of the grain dryer A is
The discharge cylinder part 41 of the machine 4 must be equipped with both a means for switchingly communicating with the extraction gutter 43 provided at the bottom of the discharge cylinder part 41 and a means for removing residual grains. Not only is the mechanism cumbersome, but the means for removing residual grains requires a slide shutter provided at the bottom of the conveying gutter 3 or a rotatable bottom plate of the conveying gutter 3 to completely remove the residual grains. There is a problem in that the opening and closing operations must be repeated several times.

The present invention has been made in order to solve these problems occurring in conventional means, and the means for removing residual grains in the conveying gutter is alternately switched between the ejection tube and the take-out gutter. It also serves as a switching means for communication,
